Abstract Background Information about genotypes and associated risk factors in hepatitis C virus HCV infected patients in Iran is limited. The aim of this study was to identify the HCV genotypes and associated risk factors in a group of HCV infected patients from Iran. Results Genotyping analysis was performed in l56 patients with positive anti-HCV and HCV-RNA. Patients were questioned concerning documented risk factors. Genotypes l and 3 were found in 87 and 45 patients respectively. The most frequent HCV subtype was la followed by 3a and lb . There was no statistically significant difference between the risk factors analyzed and the acquisition of HCV infection. We further found that l8 40 and l7 patients that were intravenous drug users IVDU
